The transfer of electric power in bulk, especially what is done from the electric power plants to different locations is commonly referred to as the electric power transmission. There are usually huge networks of wires and cables that are setup in order to facilitate the transfer of electric power from one location to another.
The network is given different names at different places but the main aim of the grid is to ensure the transfer of power from multiple input points to multiple output points at places known as stations or substations. The electricity that passes through these lines is generally high voltage electricity and hence there are multiple mechanisms by which the same can be done at different places for different purposes.
The electrical wires that are visible up in the sky connected to different poles are one of the most common forms of power transmission. It connects different substations across locations to transfer the high voltage electric power. Aluminium alloy is what generally used as the power transfer material, as it is way cheaper than copper. In most of the cases, the transmission is done via bundle conductors wherein several different lines and cables are used parallel to one another in order to make sure that minimal energy is lost during the process of transfer.
Not only can the electric power be transmitted via the overhead wires, there are also underground mechanisms that make use of special underground wires and are usually able to withstand water and extreme weather conditions. The main reason why the underground electric power transmission is not used as frequently and commonly as the overhead transmission is because the underground system is difficult to establish and is also costlier. Not only that, the overhead transmission systems are better at costs but they also transmit much more power than that transmitted by the underground systems.
